Synthetic Thermic Fluid

Thermic Fluid is the heating media which transfer the heat in close loop cycle.
It is available in two forms……….
Mineral heat transfer oil.
Synthetic heat transfer oil.
Mineral oil can withstand maximum temperature up to 280˚C. Synthetic oil can withstand maximum temperature up to 310˚C.
Continuous use of thermic fluid systems results in to deteriorating of Thermic fluid.
The main causes for deterioration are oxidation & cracking.
Oxidation: Oxidation at higher temperatures causes formation of sticky carbon. This causes choking of the system & reduced heat transfer efficiency & also produces acidic products. These add to viscosity of the oil along with increase in corrosion rate at internal parts of thermic fluid heating system.
